How to insulate walls with voids
According to journalists ProfiDom.com.ua, the domestic company Elit-Plast, a manufacturer of penoplasting Penoboard (Penobord), has developed a common thermal insulation system with XPS slabs, which is ideal for regions with severe weather conditions, such as rainy and windy coastal or sunny and hot southern.
In the first case, the thermal insulation of the walls protects from the cold, in the second – from the heat, while maintaining a comfortable temperature inside the buildings.
XPS Penoboard thermal insulation system
According to construction standards, the internal wall of the building must withstand the static loads of the roof, ceiling and wind forces. The thickness of the walls of a two-storey building is on average 24 cm and 17.5 cm in the places where the service pipes can be installed.
In the cavernous walls, moisture can penetrate the insulation layer both inside and outside the building: in the form of water penetrating through open gutters, or vapors. The Penoboard material provides low thermal conductivity and water permeability, creating a durable and resistant to deformation layer of thermal insulation.
Wall insulation technology by extruded Penoboard polystyrene
On a heat-insulated wall it is necessary to eliminate all available pores and roughnesses. Thoroughly clean the surface from wallpaper, putty, plaster and dirt.
Before sticking the foam polystyrene slabs of the wall to coat the primer.
By isolating the interior from inside, the glue is applied to the entire surface of the XPS plate. With external warming – it’s point.
It is inappropriate to use any means to reduce the time of drying glue and sealant – they should dry naturally for several days.
The base beacons will ensure uniform installation of the heater.
After mounting the plates of extruded expanded polystyrene proceed to the next stage of finishing work: plaster, putty, wallpapering, etc.
Advantages of Penoboard extruded polystyrene insulation:
absence of factor of seasonality (it is possible to install XPS Penoboard at any time of year);
maximum reduction of heat loss;
possibility to insulate brick, block, wooden walls (including frame structures);
long life of thermal insulation XPS Penoboard – up to 50 years;
No additional vapor barrier is required.
